Version 3.0.11 introduced spectrum markers, an exciting way to annotate the display. Version 3.0.12 takes the markers concept a step further by adding support for DX Cluster spots as shown below.
As spots arrive they are added to the display and remain for a period which you select in the options (below).
Note: Markers must be enabled if DX Cluster spots are to be shown, more information is here.
Select DX Cluster from the ribbon bar, View, Spectrum pane.
The cluster dropdown is pre-populated with a list of common cluster nodes, so all you need is a callsign to logon. You must consult the cluster administrator for access information. You are not restricted to this list of nodes, you can use any DX or CC cluster node.
(Requires build 2429 or higher.)
To send a spot your account must be registered with the cluster node, when you connect to the node you usually see registration contact information in the preamble (press the Text link).
If your account registration requires a password add it to the login information with a ':' or '/' delimiter, for example G4ELI:CodeMonkey.
Click the Spot button to show the fields - you enter the callsign and optionally a comment. Frequency is filled in automatically from the active receiver and rounded to the nearest kilohertz. Click Send Spot to send the spot, any errors are shown in the list.
To register with spider.sdr-radio.com send an email to HRDregistration@gb7mbc.net, don't forget your callsign! (Ian sysop @ GB7MBC handles registration.)
Node spider.sdr-radio.com is hosted on an Ubuntu VM under Hyper-V in the sdr-radio.com infrastructure.
If you send a 10GHz spot, for example using the QO-100 geostationary satellite you may see the spot appear twice:
This is caused by erroneous cluster nodes that use 32-bit integers when they should use 64-bit integers and also apply a 'fudge' to the frequency.
